That's an infinite list. If you restrict it to integers, then count by ones from 12 to 98.
There are infinitely many numbers between 11 and 99. Some examples are:11.00000000000001
11.000000000000010034
11.000000000000010035
12.5678
and so on.
There are 50 odd numbers between 0 and 100.Five of them (1, 3, 5, 7, and 9) are outside the range you're considering.That leaves 45 of them, including 11 and 99.
99 = 3*3*11 or 32*11
Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!
The prime factorization of 99 is: 3 * 3 * 11 = 99
It is: 3*3*11 = 99
8 of them.
9 and 11. 9*11=99 11-9=2 Seriously, put sometime into thinking through, it's not that hard.
The prime numbers for 99 are 11 and 33.
There are 50 odd numbers between 0 and 100.Five of them (1, 3, 5, 7, and 9) are outside the range you're considering.That leaves 45 of them, including 11 and 99.
There are 10 such numbers between 8 and 121 that are divisible by 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110.
There are 9 numbers between 10 and 100 that are divisible by 11. They are: 11, 22, 33, 44, 55, 66, 77, 88, and 99
The prime numbers (factors) of 99 are: 3 and 11
99 = 3*3*11 or 32*11
One way to approach this is to look at the difference between 99 and 110, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 99 and 110 are divisible by 11, the greatest common factor is 11.
Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!
11, 22, 33, 44, 55, 66, 77, 88, 99.
There are 49 even numbers between 1 and 99.
